Named after the Greek prophetess. A way of saying “I told you so” or to remind people not to complain to your ass about shit because you warned them all about the problems you saw coming a mile away.

I filed a Cassandra Claim when you hired his dumb ass so don't start in with me. I told you he was a sticky fingered shifty bastard and you still hired him so it’s your fault that he stole over $9,000 worth of stock.

I’ve got a Cassandra Claim on your boyfriend cheating on you, Beth, because I warned your ass that I saw his car parked in front of the porn store just about every night on my way home from work.
